3. Installation
This chapter describes installation of the following equipment:
Section 3.1 General-purpose Detector (except ZR22G-015)
Section 3.2 High Temperature Detector (ZR22G-015)
Section 3.3 Converter
Section 3.4 ZA8F Flow Setting Unit
Section 3.5 ZR40H Automatic Calibration Unit
Section 3.6 Case Assembly (E7044KF)
3.1 Installation of General-purpose Detector
3.1.1 Installation Location
The following should be taken into consideration when installing the detector:
(1) Easy and safe access to the detector for checking and maintenance work.
(2) An ambient temperature of not more than 150 °C, and the terminal box should not be affected
by radiant heat.
(3) A clean environment without any corrosive gases.
NOTE
A natural convection type detector (model ZR22G----C), which uses ambient air as
reference gas, requires that the ambient oxygen concentration be constant.
(4) No vibration.
(5) The sample gas satises the specications described in Chapter 2.
(6) No sample gas pressureuctuations.
3.1.2 Probe Insertion Hole
Includes those analyzers equipped with a probe supporter and probe protector.
When preparing the probe insertion hole, the following should be taken into consideration:
CAUTION
The outside dimension of detector may vary depending on its options. Use a pipe that is
large enough for the detector. Refer to Figure 3.1 for the dimensions.
If the detector is mounted horizontally, the calibration gas inlet and reference gas inlet
should face downwards.
When using the detector with pressure compensation, ensure that the ange gasket does
not block the reference gas outlet on the detectorange. If the ange gasket blocks the
outlet, the detector cannot conduct pressure compensation. Where necessary, make a
notch in the ange gasket. Conrm the external dimensions of the detector in Section 2.2
before installation.
The sensor (zirconia cell) at the tip of the detector may deteriorate due to thermal shock if
water drops are allowed to fall on it, as it is always at high temperature.
